Abstract:
This month’s Q&A features a discussion on moisture in concrete slabs-on-ground. It focuses on water migration; pH on slab surfaces; efflorescence; vapor retarders/barriers; slab curling; moisture in slabs; concrete exposure to water, sulfates, freezing and thawing, and chlorides; admixtures to stop vapor transmission; and concrete moisture and flooring installation.
